CONSTRUCTION OF METAL DOORS.

Specification of Letters Patent. 7

Patented Oct. 15, 1918.

Application'filed January 6,1916. Serial N 0. 70,658.

To all whom it may concern:

Be it known that we, HENRY R. GoeAY and THOMAS F. BERREL, citizens ofthe United States, and residents of Columbus, in the county of Franklinand State of Ohio, have invented a new and useful Improvement in theConstruction of Metal Doors, of which the following is a specification.

This invention relates to an improvement in the construction of metaldoors, with the object in view of providing a hollow fireproof doorwhich will be rigid, light and durable.

A further object is to provide a metal door which is readily assembledand cheap to manufacture.

A still further object is to provide certain improvements in the form,construction and arrangement of the several parts whereby the abovementioned and other objects may be effectively carried out.

A practical embodiment of our invention is represented in theaccompanying drawings, in which- Figure 1 represents a front elevationof the upper corner of a metal door, with the panel therein, a portionof which door is broken away to show the parts more clearly below,

Fig. 2 represents a vertical section taken in the plane of the line AAof Fig. 1

Fig. 3 represents a detail horizontal section taken in the plane of theline BB of Fig. 1,

Fig. 4 represents a detail horizontal section taken in the plane of theline OO of Fig. 1,

Fig. 5 represents a detail vertical section similar to Fig. 2,illustrating a modified form of panel molding, and

Fig. 6 represents a detail section of a form of panel molding having astrip 'removably secured thereto.

In the drawings, we have shown only a portion of a door, of which thetwo stiles are denoted by 1 and the top rail by 2.

It will be understood that the other rails, not shown, which are used inthe building of a door, will be constructed similar to the top rail.

The stile 1 is of U-shaped construction and provided along its innervertical edgeswith lateral grooves 3.

The rail 2 comprises two plates 4; having lateral grooves 5 along theirinner horithe stiles and rails at their grooved inner vertical andhorizontal edges, respectively. These spacing bars are provided withlongitudinal recesses 13 for receiving the walls of the panel recess 9.

The spacing bars 11 are arranged with the side walls adjacent to theinner walls of the stiles 1 and the spacing bars 12 are arranged withthe side walls adjacent to the inner walls of the rails 2, therebyforming convenient posts for the welding operation.

Thus it will be seen that the spacing bars 11 and 12, being locatedbetween the inner walls of the stiles and rails at their grooved innervertical and horizontal edges, and the panel and molding coacting withrecesses 13 in the bars, tend to strengthen the door at this point.

The upper edge of the door is sealed by means of a channel bar 14 whichrests upon the vertical tongues and grooves of the rails and stiles, cutaway at 15 for that purpose, so that the side walls of the channel barwill be in close contact with the inner walls of the stiles and railsfor welding.

The lower edge of the door (not shown), may also be sealed in a similarmanner.

In the form shown inv Fig. 5 the panel is provided with exterior surfaceplates 16 having an asbestos lining 17 interposed therein. In this form,the construction of the molding 7 is made with a recess 18 suitable forthe reception of the lined panel.

In Fig. 6, we have shown a modified form of panel molding in which astrip 19 is removably secured to the molding by means of a screw 20having a threaded engagement with a plate 21 secured to the molding.

It is obvious that various changes may be resorted to in the form,construction and arrangement of the several parts without departing fromthe spirit and scope of our invention; hence we do not wish to limit ourselves strictly to the structure herein set forth, but

What We claim is:

1. in a sheet metal door, a stile having oppositely disposed lateralgrooves along its inner vertical edges, a vertical spacing bar locatedwithin the stile adjacent to said grooves and having a longitudinalrecess and a panel molding provided with inwardly turned edges locatedin said grooves and a panel recess interposed between said edges, thewalls of said recess being in position to coact with the recess in thespacing bar for stiffening the molding.

2. In a sheet metal door, arail having oppositely disposed lateralgrooves along its inner horizontal edges, a horizontal spacing barlocated within the rail adjacent to said grooves and having alongitudinal recess and a panel molding provided with inwardly turnededges located in said grooves and a panel recess interposed between saidedges, the walls or" said recess being in position to coact with therecess in the spacing bar for stiffening the molding.

3. In a sheet metal door, stiles and rails having oppositely disposedlateral grooves along their vertical and horizontal inner edgesrespectively, spacing bars located with- Copies of this patent may beobtained for five cents each,

in said stiles and rails adjacent to said grooves and havinglongitudinal recesses and a panel molding provided with inwardly turnededges located in said grooves and a panel recess interposed between saidedges, the walls of said recess being in position to coact with thelongitudinal recesses of said spacing bars for stiffening the molding.

l. In a sheet metal door, stiles and rails having laterally disposedgrooves along their vertical and horizontal inner edges respectively,said rails having laterally turned tongues along their ends located insaid vertical grooves in the stiles, spacing bars located within saidstiles and rails adjacent to said grooves and having longitudinalrecesses and a panel molding provided with inwardly turned edges locatedin said grooves and a panel recess interposed between said edges, thewalls of said recess being in position to coact with the longitudinalrecesses of said spacing bar for stiffening the molding.

In testimony that we claim the foregoing as our invention, we havesigned our names this fourth day of January, 1916.
